Answer

Answer:

C. Its discs allow it to coordinate movement with other cells.

Brief Explanations:

Cardiac muscle has intercalated discs. These discs contain gap junctions that enable electrical signals to pass between cardiac muscle cells. This allows the heart muscle cells to contract in a coordinated manner. Spindle - shaped cells are a feature of smooth muscle, not cardiac muscle. Striations are present in both skeletal and cardiac muscle, but the striations themselves do not explain how cardiac muscle coordinates its function. Multinucleated cells are a feature of skeletal muscle, not a key structural feature for the function of cardiac muscle in terms of coordination.
